This design is a spin-off from one I covered in February. Both are transformer units; the first was a crib that transforms into a bed to accommodate a growing child. This unit doesn't become a bed, but it offers a greater range of choices to the baby market, going from a cradle to a bassinet to an add-on for a larger bed.
The three-in-one is the work of German furniture company HOKIMÖ Massivholz Kindermöbel, which specializes in making solid, handcrafted, customized, nice-looking wooden pieces. To change from the fixed bassinet to a swinging cradle, it's just a matter of releasing a lock.
Either side can be removed (without tools), so the crib can be attached to a bed, sort of like a sidecar on a motorcycle. I'm not sure that's an especially useful function- but maybe once the baby has outgrown the crib, an especially tall parent could use the defunct piece as extra room for their feet.
What I'd love to see is a single design that incorporates these three uses and that can become a child's bed as well- why not go all the way?
